You can always count on celebrities making idiots of themselves when you need cheering up, so last week I was delighted to switch on my TV and see real F-lister Alastair McGowan, who's long been off the Heat radar, standing in a freezing cold field, wielding a shovel.

From the footage it looked like Alastair McGowan had totally lost the plot and honestly believed he could hold off the combined forces of the Goverment, BAA and international business with a spade bought from the B&Q sale.

Now, to be totally honest, I have no real opinion on the Heathrow debate, not living under the flightpath means I'm not directly affected and I can see both sides of the story. I'm all for people making their point, as long as protests don't start disrupting the general public, which I'm certain this will.

It seems horribly unfair when people have saved hard for their holiday to then miss their flight or be delayed due to a go-slow on the roads, or some other futile act of sabotage. No amount of annoyance is going to change the Government's minds – if anything will, it's a well put-together argument presented along the correct lines.

Delaying flights and passengers isn't going to hit BAA where it hurts, only the general public tourists and international businessmen who we could really do with keeping onside when the UK needs all the trade it can get.

If potential tourists in the States switch on the news and see chaos at Heathrow with delays, cancellations, blockades or whatever protests are being cooked up, they are more likely to head to Paris instead, or just about anywhere else for their holidays.

The brutal truth is, the decision has been made now, it's probably best to just accept it.

I also really wouldn't recommend buying a field on the new site, you're unlikely to get planning permission to build a shed on it and with real-estate prices falling through the floor, by the time the compulsory purchase order is executed, the field will be worth less than it costs to buy a coffee in Terminal 5.

While the debate rumbles on with politicians switching band-wagons at will, I think I might get away from it all by popping along to Farmer McGowan's field and see if I can provoke him to shout "get off my land" while wildly waving his spade.
